I got my RX330 a week ago and was able to program buttons 1 and 3 to open the left and right doors respectively. After a few days button number 1 opened both doors! I thought I did something wrong so I reprogrammed button 1. This afternoon when I got home button 1 opened both doors again. I reprogrammed button 1 for the third time but I'm not sure this is going to solve rthe problem. Anybody has seen or heard of this? Thanks, Jose
